Sticky Tape: Background Information
Sticky Tape Lab
Standard Course of Study Goals and Objectives
Goal 1: The learner will develop abilities necessary to do and understand scientific inquiry.
1.01 Identify questions and problems that can be answered through scientific investigations.
1.05 Analyze reports of scientific investigations of physical phenomena from an informed scientifically literate viewpoint including considerations of:
• Adequacy of experimental controls.
• Replication of findings.
• Alternative interpretations of the data.
GOAL 8: The learner will build an understanding of static electricity and direct current electrical circuits.
8.01 Analyze the nature of electrical charges.
• Investigate the electrical charging of objects due to transfer of charge.
• Investigate the conservation of electric charge.
• Analyze the relationship among force, charge and distance summarized in Coulomb's law.
Materials
• Transparent tape
• Soda can
• Styrofoam cup.
Introduction to the Teacher
Students should know after this lesson that the force between static charges varies directly with the magnitude of the charges and inversely with the square of the distance between the charges.
Use transparent tape to set up a static charge. Place a piece of tape sticky side down on the table. Make a non- sticky handle on one end of another piece of tape by folding over one centimeter of the tape. Then put the second piece of the tape sticky side down on the first base tape. Pull the tape off quickly. This will put a static charge on the tape. Oppositely charged tapes can be made if two tapes are placed on the base tape and pulled off as one. Then the two tapes can be pulled apart. These charged tapes work in conditions of high humidity. Place the charged tape onto the edge of the table and bring various objects near the tape. These labs with transparent tape are described in detail in Electric and Magnetic Interactions by Ruth Chabay and Bruce Sherwood, John Wiley and Sons, New York, 1995. Similar labs are described in the Teaching About Electrostatics AAPT/ PTRA- PLUS Workshop by Robert Morse, American Association of Physics Teachers, College park, Md, 1992.
